outs in the inner tubes of pneumatic tiresq A further object of the invention is to provide a simple, cheaply constructed device of this character which may be readily ap plied to the tube to close the puncture open; ing therein and which, in its application, will not bruise or in any way affect; the remainder of the tube.

Further objects of the invention will appear as the following specific description is read in connection with the {l(!(f .)llll)ttlllll drawing, which liornis a part of this application, and in which Figure l an eltualion ol? the device applied to a tire big; is a sectional view through the device and tire. Fig. 3 is a perspective View of the inner n'ion'ihor. Fig. 4 is a similar view ol' the outer member. Fig. 5 is a perspective view of the clamping member.

Referring more particularly to the draw ing, 1 represents an ordinary inner tube of a pneumatic tire and 2 generally indicate-i the puncture closing device. This pui'icturc losing device ctniuiriscs a substantially sauccr-lilu: ll.'-.l( 3 having a standard l projecting .lroin its centcr concave portion, which standard is cxteriorly thrcatled and preferably hollow, as shown, to reduce the weight ot the article. A similar saucerlike disk 3, hav ng a central aperture it therein to rcccirc the .--;laudard. is provided and a clamping lil(llll)tl' con isting ol' a auban interna ly thli'eadt-d c llar or nipple H projecting; thcrcfrom also provided to clamp the nicn'iht-r: 3 and 5 together. Both -l' lhc nuunlwrs are provided wi h. annular rih.-, l) which are pressed up from their bodies, so as to prw done in the member 5 a channel it) .'hich is adapted to he outer-ed by tho it on the nuanbcr 3 or, more correctly .peaking, :-o that the rib on the member 3 will press a portion of the tube between the disks up into the channel 10. 'lhe said saucer-lilac disks 3 ant; are provided on their on :-;-'ing faces A with a. layer of canvas 10, thereby preventing the rubber l'rom chafing.

'lhc outcr edges of the disk 7 are thinneil out so as to lie lat against the outer disk 5, as shown at '11, and Suitable holes 1; are forn'ied in the disk to receive a spanner wrench or similar tool by which the clampingmeml'ierinay be threaded upon the standard 4.

In practice, the puncture is first located and an opening made in the tire at the puncture point which will be of sullicieutsize, after stretching the tube, to permit the passage of the lower disk 3. This opening may be formed by a pair of pliers having semiu-ircular cutting blades thereon and the tire folded along the puncture line so that, when the jaws are brought together, a semicircular cut is made which, when the tire is open, will form a circular opening. string is tied around the standard and the disk and the standard pulled out ol the opening, still holding on to the string whil the second disk 5 is placed down over the standard. The string then removed and the clampinp member 7 scrcwtal down upon the standard, so that the outer edge of the nipple abuts the disk and the outer edge of the disk 7 rests upon the concave convex portion of said disk. The clauiping i'nember is then tightened up by a spanner or other suitable implement.

it will be noticed that by the use ol the outer disk 5 the clamping; member will not, wear the tire in being scrmved home and that by the use of a disk of this character having the nipple 8 the tire is positively gripped around the standard and resiliently clauu ed between the outer and inner disks adjacent the edge of the same. These devicw may be made oi. any suitable material and of any Hill or of many 1--'ixcs so as to be adaptable l'or punctures or small blou'huts and may 7 c nstructed to operate upon the Hlllt'l' inc or the inner tube with equally adaau lagoons results.

llaving thus described the 'nvcnlion, who I claim as new l22-- x\ puncture repair device comprising in hr! and outer concarowonvcual disks.
